Abstract: A method for improving the cache locality of an application executing in a computer
system by decomposing the application into one or more threads and subsequently
scheduling the execution of the threads such that a next thread to be executed is likely to

Abstract: A light exposure device for a color copier has a
plurality of laser light sources (42Y, 42M, 42C, 42B)
for emitting laser beams (41Y, 41M, 41C, 41B) on the
basis of image signals of separated colors. These
laser beams are continuously deflected by a polygon
mirror (91) to allow the surfaces of the photosensitive
drums (51Y, 51M, 51C, 51B) which are provided correspondingly
to the respective light sources to be
scanned with the laser beams. Through the scanning of
the laser beams by the polygon mirror (91), electrostatic
latent images corresponding to the respective
colors are formed on the surfaces of the photosensitive
drums. At this time, a portion of a laser beam (41B)
emitted from a reference light source (42B) is received
by a light receiving element (92) and, by doing so,
a sync signal is obtained. Based on the sync signal
it is possible to control write timings of the laser
beams (41Y, 41M, 41C, 41B) emitted from the laser beam
sources (42Y, 42M, 42C, 42B). Further, register
patterns output onto a transfer belt (61) at that time
are read out by an image sensor (67) so that a shift
relative to the patterns is detected and, by doing so,
the write timings of the laser beams (41Y, 41M, 41C,
41B) are so corrected as to bring the relative shift to
zero.
